Bit CRM REST API Documentation for Developers

The Bit CRM REST API lets external applications read and write CRM data over HTTP. Requests authenticate with an API key you create in Settings → REST API; request and response bodies are JSON, and every endpoint is documented with example requests in Bash, PHP, and JavaScript.

Start with Introduction & Authentication, then jump to the module you are integrating:

• Introduction & Authentication: base URL, creating API keys, authenticating requests, response format, pagination, and rate limits.
• Leads: create, search, retrieve, update, and tag leads.
• Contacts: create, search, retrieve, update, and tag contacts.
• Companies: create, search, retrieve, and update companies.
• Deals: create, search, retrieve, and update deals, move them through pipeline stages, and list the stages.
• Products: create, search, retrieve, update, and activate or deactivate products (requires Bit CRM Pro).
• Tags: list existing tags and create new ones.
• Notes: list the notes on a CRM record and add new ones.
• Activities: list, create, and retrieve tasks, meetings, calls, and activity notes.
